Which technique provides a rapid HbA1c measurement method?

• A. High Performance Liquid Chromatography (HPLC)
• B. Tandem Mass Spectrometry
• C. Mass Spectroscopy
• D. Capillary Electrophoresis

Answer: (A)

Measuring HbA1c effectively relies on separating glycated hemoglobin from other forms and quantifying the glycated portion quickly. High performance liquid chromatography does this well by separating Hb species in a single automated run and providing the HbA1c percentage directly from the chromatographic readout. In routine clinical labs, this method is favored for speed and reliability, often delivering results in minutes per sample and supporting high-throughput testing. Tandem mass spectrometry and mass spectroscopy offer high precision but require more complex workflows, longer setup, and specialized equipment, making them less practical for rapid routine HbA1c measurements. Capillary electrophoresis can separate Hb variants as well, but in many settings it is not as universally streamlined for speed and throughput as HPLC.
